After nearly three weeks, my struts arrived (bought on eBay on Dec. 4, they arrived Dec. 28 - apparently by Donkey Express).
Unfortunately, the shipper screwed up and sent only the fronts, so I attacked that first (rears will be here next week, I'm assured).
First problem right off the bat was that I discovered that the P.O. didn't include the lug nut key with the car when I bought it. A phone call to the dealer revealed that they (the dealer) cannot get a replacement. Luckily, the PO found the key and I got it from him. On the way back, I stopped at AutoZone and purchased 4 normal lug nuts to replaced the keyed nuts.
Jacked the car/ used jack stands/ removed the tire.
Now to the strut:
The first strut took me about 5 hours over two days, the 2nd took me about 2.5 hours after I knew what I was doing.
I found that it was easiest to remove the brake caliper and hang it out of the way with some stout wire. Also, you'll want to use some wire to keep the ABS sensor wire out of the way.
Turn the wheel all the way to the right (or left, depending on which side you're working on) to gain better access to the pinch bolt holding the bottom of the strut.

This is where you'll need a very stout air wrench or about a three foot breaker bar. The pinch bolt (13/16") is easily the hardest bolt I have ever removed (successfully) from a car. I was reading over on the Taurus forum that, more often than not, they break when removed. However, I was lucky on both sides and they did not break. I bought new bolts from AutoZone, but the old ones probably could have gone back in.

At this point (after you remove the top bolts on the strut in the engine compartment) the strut will probably come out, but you'll not get the new one (with the spring fully extended) in. I found that I could remove the bolt from the lower ball joint, lever the hub assembly up off the ball joint and then off to the side (watch out for the ABS sensor - it will be in close proximity to the exposed ball joint and could get broken). I attempted to remove the ABS sensor on the drivers side, but it appeared that I would probably destroy it in the process so I worked around it).

When removing the strut from the bottom knuckle, use a hammer to knock the knuckle down enough to expose some of the "fin" with the hole in it on the back side, which fits into the slot on the knuckle. You can then use a pry device (I used the lug wrench) to pry the strut up and out of the knuckle.

Removing the ball joint will give you another 2" to work with and that should make the difference in getting the bottom of the strut into the "knuckle". I had to use an array of pry bars and my floor jack to align various components to re-assemble, lever stuff into position, etc.

I've skipped a few parts, but if you know what you're doing, the rest should be self-evident. These are just some tips that turned a 5-hour job into a 2.5-hour job. The back of the car is still "on the ground" so I haven't taken her for a test drive, but the car is sitting up nicely in the front and I expect similar results in the back.
 
By some quirk of fate, El Niño, or Global Warming, we had temps of nearly 70° here in Maine this past weekend (not bad for the first week of January) and it was perfect for working on the car.

The rear struts were nearly as joyous as the fronts.

Found this website with some handy photos:

Again, it's easier for me to work with the brake caliper removed and hung off to the side, but you may be able to work around it.

The side/torsion springs (I don't know what they're called, specifically, but they apply lateral tension to the strut) are not needed on the new struts, so you can pretty much demolish at will when you remove them. There has to be some use for that great spring steel - it's a shame to throw it away. I'm thinking maybe a catapult to take care of the neighbor's yappy dog...

But I digress.

The pinch bolts on the rear are a weird design with the bolt head in the normal place, but then another bolt shaft extends away from that for mounting the torsion springs. I used a Sawz-All and took care of the whole mess and left easy access to the bolt head.
Of course, that proved to be a waste of time because both pinch bolts (left and right) sheared upon attempted removal. Oh. Joy.

At this stage of the game, it's best if you have a stalwart drill (Craftsman or the like), some decent arm strength, and the hardest drill bits you can lay your hands on. Start small, drill through, and move up from there. About 40 minutes of drilling per side and you'll have nice new holes to put nice, new bolts in. My rear struts were junk, so I used the aforementioned Sawz-All, cut the little tab that goes into the slot in the "knuckle", ran a chisel into the slot to open it a little (the bolt head was sheared off so no tension on the knuckle) and pulled the struts out. This gives you plenty of room to work on that pinch bolt.

By the way, it is far easier to unbolt the top of the struts, compress them, and rotate the entire hub and strut away from the car (see website for pics) to work on it.

Anyway, after I had the spindle bolt hole drilled, re-assembly was pretty straightforward. When you put the new struts in (or replace the caliper) be careful of how you route the brake and e-brake lines. I ended up having to remove my brake line, re-route it to the proper place, and then bleed the brakes because I wasn't paying attention when I put the strut in (and I already had rotated it back up into the car and bolted in the top mounts before I discovered my error).

Another DOH! moment was when I attempted to remove the sway bar bushing on the passenger side (per every set of instructions I saw) and I broke the bolt holding the bushing in place. So, now I'll have to have that drilled/tapped and re-bolted by somebody with a lift. On the other side, I found that I could just lever the sway bar down enough to get the mounting bolt out so I advise you to NOT unbolt the sway bar bushing and avoid more broken bolts.

All back together now, and the car rides great. Of course, an '86 Yugo rides better than a Conti sitting on its bumper stops. If you choose to do this job yourself, plan to spend some time with frozen bolts (especially the spindle bolts). Look on a broken bolt as an opportunity to augment your tool collection with some decent drill bits. But certainly do the job yourself and save the $1000 (plus parts) or so that Midas will charge you.
 
you found the way I did the rears on my 91. pretty much the same, except I didn't break both pinch bolts, just the one on the driver side. However, I did snap a sway bar link in 2 trying to get them rusty nuts off. luckily, they are the same as the taurus uses, and the local parts shop (which is open all of 4 hrs on sat, not at all on sunday) had a nice heavy duty set in stock (about 2 times the diameter as the stock ones). I also did NOT remove the strut-to-body bushings, but just pryed the link out of the end of the bar.

Since I was putting air struts back on, I had to use the damn spring. I have found about the only way to put that back on (they came off pretty easily) is to put a small jack under the end of it and jack the spring back up (will almost lift the car off the jack stands in the process) and hope the hole lines up with the shoulder bolt, then you pry it onto the bolt and start your nut to hold it on there until you get the other side up.

I am not positive you can get rid of the springs tho, I dont see why they are on there, but I am pretty sure taurus's have them, and they don't use air struts, but coil struts similar to what you put on. Since the majority of the suspension parts are the same (or very similar) to the taurus, it would seem logical to me that the springs should be there.

I was lucky in that I had a donor car (southern car, no rust) with nearly new struts in which I had an ample supply of spare parts/bolts. I mearly replaced all my rusty bolts with new (slightly used) non-rusted bolts/nuts when I put it back together. it took me about an hour to pull the 1st strut on the parts car (not knowing exactly what order to do it), and about 30 mins to pull the 2nd. The rusty car.. well, 5 hrs for the 1st, (to pull, and didn't break the pinch bolt), and about 5 hours for the 2nd (after knowing what to do, and breaking pinch bolt, as well as several others, glad I saved all them southern bolts).

reassembly, well, other than fighting with the torsion spring, 30 mins each. I spent an easy 3 hours on the 1st trying to figure out how to put that back in (in sub-freezing weather too). 2nd torsion spring went pretty quick at 30 mins at most.

Oh, and every nut and bolt in the suspension is metric, its just a coincidence that some come out to the same head size as SAE.
 
Ok, so we've got a work log, but how does the ride feel.
I'm at a crossroads of continuing with air or convert.
Most people here say keep the air, what do you two think?
 
im on air, so I cant comment on the spring ride. It probably will soften a little after some miles are put on it, once the springs take set.
 
Mine rides great on the new springs (well, used springs). Very calm, smooth ride. And much cheaper than replacing the air ride bags/struts (I bought 4 slightly-used struts/springs for the price of one air ride strut - $249 shipped).
Also, there are lots of options for replacements if I don't like the ride. I even saw some lowering springs on eBay, but we'll leave that to teenage drivers of Hondas.

The side-torsion springs do not mount on to the new Taurus struts - if you look at pictures you'll see that there is no "recepticle" on the side of the strut tower to slide the upper "U" portion of the spring into to mount it.
To be safe, I checked a 95 Taurus in a parking lot and no spring in sight.
I think that they were there to compensate for the fact that the air bag presents no side-to side strength. The coil springs on the Taurus, although "springy", do present some resistance to "racking" and don't need the torsion spring.

Of course, this is all my opinion.
 
Gearhead,
I Just Finished Putting Springs On My 92. I Got Them From Strutmaster And It Was Not That Bad. I Learned As I Went But Only Took 1.5 Days Not Working Too Hard.

After a few months of driving on the struts/springs, I still like them very much. However, I believe the used rear struts came off a flood car (i.e. Katrina), because when the temp is sub-freezing here for more than a day at a time the left rear strut freezes up solid as a rock!
I recommend buying new from Strutmaster - they've got a great rep and I've never heard anyone complain about the parts. My used parts... not so much.
I'm going to purchase some Taurus rear struts and I already have new springs to go on them.
Still haven't replaced the broken sway bar bushing bolt so I know the rear ride isn't what it should be, but it's been too cold to get out there to fix it. It only clatters and clanks when I go over railroad tracks. :shifty:
 
I picked up a conversion set the other day on ebay, came to 530usd shipped to canada.
Not a fantastic price and before you all jump and say I should have gone with strutmaster, I know, I checked them out and they wanted 200+$ to ship to canada, in the end I saved a little over 100$
Still waiting for them to arrive.
My plan for installing them is to rent a tool bay and get some friends who are better with cars than me.
Do you guys think with 2 or 3 guys we could get it done in an afternoon?


Also, I've been thinking over the pros of converting and I just wanted to share them, more to convince myself that I made the right decision.
1) Hopefully never have to worry about them again
2) Quieter ride without that crazy compressor kicking in
3) Free up some power for my stereo
4) Hopefully I'll find a smoother ride because I'll be on a new set that isnt 13 years old (This last one is stretching it a bit I know)
 
yea, I think a couple of guys with the right tools can get em installed in an afternoon. key is to prep every nut, bolt, fastener with lots and lots and lots and lots (did I say lots?) of penetrating oil every couple of days for at least a week prior to doing the job. Otherwise you WILL be busting bolts and such, and there is a couple of unique bolts there.
 
I was wondering about the torsion springs myself, I converted my Conti to coil struts about a year and half ago.
